Are you referring to the online analyzer for the H2S/SO2 ratio in the sulfur recovery unit? An experienced operator can analyze and make judgments based on the temperature of the reaction furnace under different operating loads, the temperature rise in each reactor, and the amount of gas used by the incinerator. If necessary, air distribution can be roughly determined by comparing the corresponding historical trend curves.

Calculate the air supply based on the concentration of acidic gases, in a scientific manner. 3. Observe the reaction temperature of the bed layer, and note its trends. 4. Check the color of the smoke coming from the chimney, relying on experience
An experienced operator can control the air volume to the main combustion furnace based on the temperature of the reaction furnace under different operating loads. Another factor that can be used as a reference is the temperature of the exhaust furnace.
1. Contact the instrument repair technician for analysis. 2. Conduct manual sampling analysis by reducing the frequency to half of its original value. 3. Based on experience: if the temperature of the acid gas furnace rises, there is less acid gas; if the temperature of the exhaust gas furnace is high, there is more acid gas. 4. Check the temperature of the bed layer – an increase in its temperature indicates more O2. haha, this is just my personal opinion for reference only
Based on the temperature rise in the hydrogenation reactor, increase the air supply to the sulfur production furnace appropriately. Control the upper limit of the bed temperature in the hydrogenation reactor, but avoid overheating and SO2 penetration.
The 2-to-1 analyzer is broken; we still have sulfur dioxide analyzers and oxygen content analyzers. We can make gradual adjustments by manual air distribution, and the results will be pretty much the same as those obtained with automatic air distribution, but the operator in charge will have to work much harder.
Thank you all, experts; I’ve learned a great deal
If there is a hydrogenation reactor: 1. It is possible to determine whether the air supply is appropriate based on the temperature rise of the hydrogenation reactor. Under normal conditions, the temperature rise is around 30 degrees. If it exceeds 30 degrees, it indicates heavy air distribution at the front. 2. With the composition of acidic gases remaining constant, there is a certain proportional relationship between the furnace temperature and the amount of acidic gases. By calculating daily operation records, the corresponding ratios can be determined to guide production. 3. The temperature rise of the bed layer is also related to the air distribution. The proportional relationship should be found through statistics. If there is no exhaust gas, an appropriate amount of peroxide can be used to increase the level of sulfur dioxide for treatment.
Which online analyzer? There are many for sulfur recovery. There are online oxygen analyzers, online hydrogen analyzers, hydrogen sulfide to sulfur dioxide ratio analyzers, etc. Active participation: handshake
Check the furnace temperature, the exhaust gas temperature, and normal operating conditions
